About this 1.33ct natural round diamond

This 1.33ct natural round sits in the one-and-a-quarter to one-and-a-half carat band, graded H colour (near-colourless) and I1 clarity (included), with a standard cut grade and certified by IGI 516281200. Listed at 6 retailers as of October 30, 2026, with a 51% spread between the cheapest and most expensive listing. That is exactly the kind of price-discovery gap Carat Hunter was built to surface. Cut grade matters more than carat or clarity for visible brilliance. If you can shift budget toward an Excellent or Ideal cut, do it before chasing higher colour or clarity.
